The model donned a silky, gaping frock that gave onlookers plenty to admire as she co-hosted a swanky bash in LA.
Striking a repertoire of poses on the red carpet, the Brit beauty confidently paraded her stunning physique at the Burberry Body event.
Sporting shampoo-ad hair and high heels, Transformers 3 star Rosie mingled with guests including actress Kate Bosworth.
The leggy pin-up has never been shy of exposing her flesh, and recently revealed stripping off for a mag was a doddle.
She said: "Going topless for Vogue wasn't a big deal at all because of the way it was done.

"It was one of the most enjoyable and tasteful shoots I've ever done. I am so proud of it."

But Florence Welch has found a different way to cope ? by developing an obsession with rising Hollywood actor Ryan Gosling.
The singer broke up with long-term boyfriend, literary editor Stuart Hammond, earlier this month, and has been getting over it by staying in and ogling the star of hit movie Drive on DVD.
She said: "My friend Hannah and I have become really obsessed with watching Ryan Gosling films.
"We especially watch them on tour, because you don't go out as your friends aren't around. I haven't met him yet but we feel like we have because we've basically got his back catalogue."
Ryan might be in for a shock if he ever made it back to her hotel room, though. The Florence and the Machine frontwoman says bland accommodation bothers her so much that she covers the walls in loads of blankets.
She said: "I get really bummed out in sterile hotel rooms so I always have a lot of shawls and scarves with me. I hang up all of my dresses to cover the walls and ceiling, so everything's always everywhere."
The star was back in her hometown on Tuesday, performing a one-off gig at London's Hackney Empire.
She wowed the crowd with songs from her new album Ceremonials ahead of its release next week.
After the outstanding gig, she celebrated with an aftershow knees-up in a proper East End boozer, forking out on drinks for the whole pub.
Her DVD player must have enjoyed the break...

Shane Meadows has been lined up to film the band's progress as they prepare for their eagerly-awaited comeback shows next summer. The acclaimed director was at the quartet's press conference last week, as they announced their new shows. And a newspaper today reports that industry sources have confirmed the commission, although the band have said a decision is due in the next five weeks. Sheffield-born Shane shot to fame in 2006 with his Bafta-winning film about a group of skinheads in 1980s England. Ian Brown, John Squire, Gary 'Mani' Mounfield and Alan 'Reni' Wren officially announced their comeback last Tuesday, although The Sun had revealed their intentions back in April.

And frontman Ian made no secret about the scale of their ambitions now that they're back.
He said: "Our plan is to shake up the world. We're gonna go around the world next year.
"We're going to start off in Manchester and play two big gigs. This is not a trip down memory lane, we are doing new songs.

"We are going to do what we did the first time and ride it 'til the wheels come off. And let's face it, the wheels did come off.
"We'll keep writing and if it hits our standards, we'll go with it. We're not here to destroy anything. It's as precious to us as it is to someone who has followed us for years.
"I've heard a few people say, 'You shouldn't do it, you're going to destroy the legacy'. But that's not our intention."
Guitarist John described how the reunion came about.
He said: "When me and Ian met by chance it changed everything. In some ways it felt like 15 years ago was yesterday. I just couldn't see a comeback happening and I resented the fact that people were trying to force it on me.
"Everything changed when me and Ian started seeing each other again.
"It was surreal. We went from crying, laughing about the old days, to writing songs in a heartbeat. In some ways it's a friendship that defines us both ? and it needed fixing."
The 222,000 tickets for the group's three shows at the end of June at Manchester's Heaton Park sold out within 14 minutes of going on sale.
She bumped into him while on a boozy night out in Hertfordshire with her mates.
Sunday Girl, real name Jade Williams, said: "It was very random.
"We were out drinking near the X factor contestants' house and we bumped into Johnny and his two massive minders.
"He was very sweet but we went into one bar and he said it was too posh for him.
"It was hilarious."

Model Clair Meek, 23, had a baby boy at Crosshouse Hospital in Kilmarnock.
Last night a friend said: "Clair was determined she was going to have their baby in Scotland.
"They are the happiest people in the world. They are so thrilled and proud.
"The two of them are so in love and now they have a beautiful baby son."
James, 24 ? who plays sex fibber Jay in the hit E4 hit comedy ? proposed to Clair, of Galston, Ayrshire, last month.
The 51-year-old singer fears there is no future for the band and he, Larry Mullen Jnr, The Edge and Adam Clayton could part ways in 2012.
He added: “I’m not so sure the future hasn’t dried up. It’s quite likely you might hear from us next year – but it’s equally possible that you won’t.”
The music legends, together since 1976 and worth €327million, are in the recording studio after finishing their record-breaking 360 Tour.
BONO has dropped a bombshell on loyal fans – by suggesting that U2 might call it a day next year.
The legendary rock band is about to re-release their 1991 album Achtung Baby and recently completed the highest-grossing tour of all time.
But frontman Bono, 51, is uncertain about what’s ahead.
He revealed: “I’m not so sure the future hasn’t dried up.
“It’s quite likely you might hear from us next year but it’s equally possible that you won’t. We have so many [new] songs, some of our best.
“But I’m putting some time aside to just go and get lost in the music.
“I want to take my young boys and my wife and just disappear with my iPod Nano and some books and an acoustic guitar.”
He admitted that band mates Larry Mullen, The Edge and Adam Clayton were sick of him questioning whether they had a future in music saying: “The band are like, ‘Will you shut up about being irrelevant?’”
But their frontman hinted that their No Line On The Horizon album might be their last. And it seems Bono isn’t the only one getting cold feet.
The Edge recently admitted that trying to find a new sound led to what he called “a potentially career-ending series of difficulties.”
But there are some who could never imagine a music world without the legendary rockers.
The re-issue of Achtung Baby is a lavish look back at the album that cemented their place in rock history.
But ironically Bono said it was this look back that gave him ideas for the way forward – if U2 decide to carry on. He added: “Being forced to look back at this period reminds me of how we might re-emerge for the next phase.
“And that doesn’t mean that you have to wear some mad welder’s goggles or dress up in women’s clothing. Reinvention is much deeper than that.”
